A solution of 291 mg (0.95 mmol) N-(2-Bromomethyl-4-methoxy-phenyl)-N-methyl-methanesulfonamide in 15 ml of DMF was treated with 45 mg (1.14 mmol) 60% NaH and the reaction mixture was stirred at 75° C. for 4 hours. The reaction was quenched with water and extracted with ethyl acetate. The organic layer was dried over sodium sulfate, dried and evaporated. The residue was passed through a short plug of silica gel eluting with 25% ethyl acetate in hexane. There was obtained 123 mg (57%) of the desired product. Mass spectrum APCI (m/z) 228 (p+1).
